How Foreigners Claim Korean Private Health Insurance (Silbi): Required Hospital Documents, Photo Claims, and Payout Hacks

Updated September 2026  |  ToolWise Editorial Team
Most long-term foreign residents in South Korea know about National Health Insurance (NHIS). However, many expats, foreign workers, and students also pay for supplemental private health insurance—commonly known in Korea as Silbi or Silson Insurance (실손의료보험).

Silbi insurance covers 70% to 90% of out-of-pocket medical expenses that national insurance doesn't pay, including expensive MRIs, ultrasounds, manual physical therapy, and prescription drugs.

Yet, thousands of foreigners leave money on the table every month because they don't know which specific Korean documents to request at the hospital desk or how to submit claims directly from their smartphone without speaking fluent Korean. Here is your ultimate step-by-step guide to getting your medical bills reimbursed.

📄 Step 1: The 3 Mandatory Documents to Ask Your Doctor For

When you finish your medical consultation or treatment, you must ask the hospital reception desk for specific paperwork before you leave. If you only bring a simple credit card payment receipt, your insurance claim will be instantly rejected.

✅ Exact Korean Terms to Show Hospital Reception Staff:
  • 1. Detailed Itemized Medical Bill (진료비 세부내역서 - Jin-ryo-bi Se-bu-nae-yeok-seo): Breaks down covered (급여) vs. non-covered (비급여) hospital costs line by line.
  • 2. Official Medical Fee Receipt (진료비 계산서/영수증 - Jin-ryo-bi Gye-san-seo/Yeong-su-jeung): Shows the total official amount paid, national insurance contribution, and your out-of-pocket co-pay.
  • 3. Prescription / Medical Confirmation showing Disease Code (처방전 or 진단서):
    • For Minor Clinic Visits / Pharmacy Claims: Ask for a duplicate prescription copy containing the KCD Disease Code (질병분류기호). It is usually free!
    • For Hospital Stay / High-Cost Treatments (Over ₩100,000): Ask for a formal Medical Certificate (진단서 / Jin-dan-seo) or Outpatient Confirmation (통원확인서).
💡 The Free Pharmacy Trick: When picking up prescribed medicine at a Korean pharmacy (약국), ask the pharmacist for a Pharmacy Fee Receipt (약제비 영수증). In Korea, the itemized breakdown and disease code are often printed right on the paper bag that holds your medication!

📱 Step 2: How to Submit Claims via Smartphone Apps (No Paper Forms!)

You do not need to mail physical paper documents or visit an insurance branch office. You can complete your entire claim in under 3 minutes using smartphone apps.

Method A: Mainstream Super-Apps (Toss / Kakao Pay)

If you don't want to navigate complex insurance company apps written entirely in Korean, mobile financial apps like Toss (토스) or Kakao Pay feature built-in claim aggregators that route your documents to almost any Korean insurance company.

  1. Open the Toss App ➔ Tap [All / 전체] ➔ Search for "Hospital Bill Reimbursement" (병원비 돌려받기).
  2. Select your private insurance company (e.g., Samsung Fire & Marine, Hyundai Marine, Meritz, DB Insurance).
  3. Enter your bank account number where you want the cash payout deposited.
  4. Use your phone camera to take clear, flat photos of your 3 hospital documents.
  5. Tap Submit (신청하기). Review takes 1 to 3 business days, and the cash is transferred directly to your bank account!

Method B: Direct Insurance Carrier Apps

If your policy was issued directly by a major carrier (e.g., Samsung Fire & Marine, Meritz, Hanwha), download their official mobile app, complete identity verification via your Korean mobile phone number or PASS app, tap [보험금 청구 / Claim Insurance], and upload photos of your paperwork.


⚠️ Common Pitfalls That Lead to Rejected Claims

⚠️ Top Mistakes Foreigners Make:
  • Missing KCD Disease Code (질병코드): Insurance companies will reject claims if the documents do not state an official medical diagnosis code (e.g., J00 for common cold, M54 for back pain). Always ensure the code appears on your prescription or medical confirmation note!
  • Simple Credit Card Slips (카드 매출전표): The small printed card slip from a credit card machine only proves payment was made; it does not show medical details. Insurance auditors cannot process claims using card slips.
  • Cosmetic & Elective Exclusions: Silbi insurance strictly excludes purely cosmetic procedures (botox, laser skin care, acne care), routine health checkups, non-prescribed vitamin IV drips, and vision correction surgery (LASIK).
  • 3-Year Claim Deadline: Under Korean Commercial Law, insurance claims must be filed within 3 years from the date of medical treatment. Don't throw away old hospital receipts!

❌ Summary Checklist: Claim Requirements by Cost

Treatment Type Expense Level Required Documents
Minor Clinic Visit (Cold, minor skin rash) Under ₩30,000 – ₩50,000 Official Medical Receipt + Detailed Itemized Bill
Pharmacy Prescription Any amount Pharmacy Fee Receipt (printed on medicine bag)
High-Cost Outpatient / Testing (MRI, Ultrasound) Over ₩100,000 Official Receipt + Detailed Itemized Bill + Medical Confirmation (with Disease Code)
Hospital Inpatient Stay Overnight hospitalization Discharge Summary (퇴원유인물) + Medical Certificate (진단서) + Itemized Bill

Never pay full out-of-pocket prices for non-covered medical treatments in Korea if you have Silbi private insurance! Show receptionists the Korean document names, snap clear photos of your receipts, and submit them through Toss or your carrier app to get your cash back within days.
